SWITCH FROM GAS TO OIL AND SAVE BIG
Why should I switch from Gas to Oil?
One of the reasons so many islanders are switching to an oil fired central heating system is because of the lower operating costs.
Switching from gas to oil can save you a significant amount on your energy bills, and also provide a greener alternative to the high cost of switching to electric, by being able to run an oil boiler on renewable heating oil.

Jersey Residents - Gas to Oil

Switching from a gas system to an oil system can save you up to £11,800 on fuel costs over the next 5 years.
For just £200 per month we will:
- Install
- Maintain
Your new oil-fired boiler and give you a FREE full tank of heating oil (up to 1000 litres) to get you up and running. Usually this would cost £882.00, filling up an 1000 litre oil tank.
Full Breakdown of Fuel Cost Savings over 5 years if you were to switch from Gas to Oil system
Based on a medium sized house with a 26kW condensing boiler*
Annual cost of running on Gas without servicing included is:
£3,932.66 x 5 Years = £19,663.31
Annual cost of running on Kerosene Oil without servicing is:
£1,556.2 x 5 Years = £7,781.21
TOTAL SAVING OF £11,882.10^ ON FUEL RUNNING COSTS WHEN YOU SWITCH.

How much will it cost for me to get an Oil Boiler installed?
The monthly payments of £200 will cover the cost of the installation and maintenance of the boiler over 5 years. The installation of the boiler alone usually is £12,000, so if we break this down in monthly payments:
£12,000 / 60 months (5 years) = £200 per month
With our offer, when you make the switch you will also get free servicing worth £135.40 per year (£677.00 over 5 years).

FAQs
What about Guernsey and Jersey government potentially banning the use of boilers than run on fossil fuels?
The boilers that we install are also able to run as a renewable heating system too. All you have to do is change your fuel to our renewable heating oil. Our renewable heating oil is a premium quality second-generation biofuel made from renewable, sustainable raw materials, such as used cooking oil and waste fats. This is NOT a fossil fuel, so any regulations local governments may implement in the future, there is no need to panic and rip out your oil boiler. You just need switch the fuel you use.
How much is it going to cost me to switch?
Switching to oil can significantly reduce your monthly heating bill and annual heating expenses. However, the cost of converting your heating system to oil is a comparatively small investment, when you factor in the potential savings over five years. Enjoying a lower monthly heating bill is one of the main reasons people switch from gas to oil. We also offer interest free credit for up to 5 years.
How long will it take to switch from gas to oil?
Every home is different, so we’ll visit you and work with you to recommend the best solution for your needs. But as a guide you can expect the conversion to take 4 to 5 days.
Who manages the switch?
We can manage the whole project from start to finish. Our team will personally ensure every stage is handled professionally and efficiently from the estimate right through to installation, servicing and maintenance.
How do I get oil?
You will automatically be signed up for our Planned Delivery Service. You can rely on us to ensure that you have oil in your tank when you need it as we automatically arrange the delivery. Because this is more efficient for our deliveries, you benefit from the savings that we pass on to you.
By doing this, it makes our deliveries more efficient, with any cost savings passed directly onto our customers. And it’s more convenient because you don’t need to be at home when we call, so long as your fuel storage tank is in an accessible location, we can make the delivery.
Kerosene is the most widely used fuel used in domestic central heating systems in the Channel Islands, so we often refer to it as home heating oil or domestic heating oil. It is chosen for its winter performance, affordability, and because it offers a cleaner and more efficient burn compared to diesel. Once you have taken delivery of your fuel, it is there for you to use as you need it. With oil, there are no differences in price when you use it throughout different periods of the day, no standard charges, no different tariffs the price you pay when you order the fuel, is the fuel price.
What about servicing once the switch is made?
As part of our switch from Gas to Oil offer, we have included free servicing for 5 years. We do offer a variety of boiler maintenance services to ensure your heating system runs safely and efficiently all year round.
Is oil fired central heating energy efficient?
A professionally installed quality oil fired central heating system should be every bit as efficient as your gas system, if not a little more in some cases. Oil fired condensing boilers provide more efficiency by recycling waste flue gases. The CO2 emissions for oil fired heating are, using an efficient boiler, no greater than normal gas. Typically, a new oil-fired boiler will have an efficiency of 92-95%.
Concerned about the environment?
In addition, to our standard kerosene, we offer 100% renewable heating oil. If you want to make the move away from fossil fuel, our renewable heating oil is the solution.
You could also consider a hybrid (or dual fuel) heating system which combines an oil boiler with a renewable heating system such as a heat pump.
As with all heating systems, regular servicing and modern heating controls will help the boiler burn more cleanly and your system to run more efficiently.
Do I need to change my radiators if I switch from gas to oil?
There’s no need to change your radiators when you switch.
All that is changing is the heat source. Put simply heating oil is normally used in a ‘wet’ heating system, where an oil-fired boiler heats the water, then provides central heating via radiators and hot water to the taps in your home.
The main difference between gas (mains or portable) and heating oil is that heating oil is delivered by road and stored in an oil tank somewhere outside your home. If you live in an apartment, there may not be enough space to site the tank and so conversion would sadly not be possible.
Are all your installers qualified to fit a new boiler and tank?
Rubis have been installing oil fired central boilers in the Channel Islands for over 70 years. Our engineers are OFTEC trained so you can be sure of the highest professional and technical standards.
Our experienced engineers can handle the entire gas to oil conversion, and we offer a range of products from leading manufacturers, which we are fully qualified and accredited to install and maintain.
We'll automatically sign you up to Planned Delivery.
So you can SAVE 1pence per litre and SAVE time and leave us to ensure your tank is always topped up.
